Log Message:
-----------
Unit tests with zero, one, two join queries are running against the query engine.
Folded in updates from mroy for DistinctSPOIterator and DefaultGraphSolutionExpander which reduce the cost of default graph queries when there are a large number of graphs in the "default graph" data set.

Log Message:
-----------
[branch dev-btm]: CHECKPOINT- - added smart proxy implementations of the transaction service and shard locator (metadata) service. Also made changes to allow those smart proxy implementations to be started by the ServicesManagerService or BootManager, as well as added new and changed current tests to run against either the smart proxy implementation of those services or the purely remote implemenations. Note that this work is still incomplete, and so includes numerous debug println's and BTM markers; which will be cleaned up in the final commit. Note finally that this changeset also includes hand-merged changes from the trunk for the following changesets: 3434, 3435, 3436, 3437, 3441, 3445, 3447, 3457, 3458, 3459, 3460

Revision: 3455
http://bigdata.svn.sourceforge.net/bigdata/?rev=3455&view=rev
Author: thompsonbry

Log Message:
-----------
Identified some problems with using variable arity for SPOPredicate and have reverted to using arity/4 at all times but allowing null for [c]. This decision should be reviewed, but I wanted to get as many of the unit tests running as possible right now. For the same reason, I have modified Predicate to allow more than one relation name (for RelationViews). The truth maintenance code currently depends on this, so by allowing this again we can validate more of the test suite.
There is a problem in AbstractBOp#clone(). The Java clone() semantics provide field by field copying. However, bop's need deep copy clone() semantics. I've introduced an AbstractBOp(AbstractBOp) constructor which does the deep copy for args[] and the annotations, but it still relies on AbstractBOp#clone() to handle recursive deep copying. I think that the right way to handle this is to implement clone() at those levels where new fields are defined. If the only place where we define fields is on AbstractBOp, then we could just implement clone() there and have it construct the appropriate object using a copy constructor for the concrete bop class whose signature is FooBop(FooBop).

Revision: 3452
http://bigdata.svn.sourceforge.net/bigdata/?rev=3452&view=rev
Author: thompsonbry
Date: 2010-08-19 21:07:19 +0000 (Thu, 19 Aug 2010)
Log Message:
-----------
I raised the getFromKey() and getToKey() methods onto IKeyOrder, defined an AbstractKeyOrder, made the various existing implementations derive from that, and modified SPOKeyOrder to override a protected inner method which handles the encoding of a single component of the key so it can do the right thing with the IVs. I moved the SPOAccessPath#init() logic into AbstractAccessPath, which makes the fromKey and toKey final and AbstractAccessPath is no longer abstract and could be renamed at some point.
I have setup some unit tests in com.bigdata.bop.ap where I am starting to work through testing bop evaluation in the context of a simple relation "R" and relation element type "E" which are defined in that package in the test suite. See TestPredicateAccessPath in that package in the test suite.
I would like to get this to the point where we are using the annotated bops as we plan to use them for scale up/out query.
I would like to test the ability to use bops to describe filters (IElementFilter) and constraints (IConstraint) on IPredicates.
I plan to add IConstraint's to IPredicate. We will renaming IPredicate#getConstraint():IElementFilter as getElementFilter() and add an IPredicate#getConstraint():IConstraint method. We can use the IConstraint on the IPredicate to validate what used to verify "rule" level constraints and this will let us customize which constraints we verify where (if we need to do that).
I also want to use an optional "variablesToKeep" annotation do things like stripping off undesired variables (when it is not specified we pass along all variables).

+- Distributed query execution pattern:
+
+ The historical pipeline join propagated evaluation from left to
+ right. This needs to be revisited in now that we are dealing with
+ operator trees. Operator trees lend themselves naturally to top-down
+ evaluation. While I think that we can do top-down evaluation of the
+ operator tree for scaleup, the distributed query execution logic is
+ more complicated and top-down evaluation is not compatible with
+ distributed evaluation because joins must run for different shards
+ based on the partition identifier associated with each bindingSet[]
+ they receive.
+
+ What we been doing is pushing binding sets along propagating joins
+ at specific shards onto nodes together with those binding sets.
+ This was a left-to-right evaluation strategy when the IRule was just
+ an ordered array of tails on which we needed to read. However, now
+ that we have an operator tree it would correspond to a bottom up
+ evaluation of a left-deep tree where the right operands were always
+ access path reads. That makes my head hurt just a bit when I
+ consider that the bottom up evaluation would also be "partial" as
+ binding sets appear.
+
+ For a given incoming IBindingSet[] chunk we will continue to do
+ exactly what we have been doing, but the surrounding logic needs to
+ be replaced. Starting a "join" (at least for piplined scale-out)
+ needs to merely register a join task factory that will handle
+ binding sets as they arrive.
+
+ I am thinking that the way to handle this is to send the query
+ identifier, join operation identifier, and partition identifier
+ along with the client's proxy object, the senders operator
+ identifier, and the senders's service identifier. If the node (a
+ data service) which receives that RMI message has not seen the query
+ yet it uses RMI against the client's proxy to fetch the query and
+ then "starts" the query on that node. Starting a query would merely
+ allow execution of the operators described in the query plan on the
+ node once they had sufficient data to run. The current pipeline
+ join is a chunk-wise nested index join. It runs one pass each time
+ it has a chunk of binding sets for some shard. Query termination
+ would be controlled by the client. It would instruct all nodes
+ known to be running the query to halt execution for that query.
+ Even if a node misses that message, it will find out when it tries
+ to send intermediate results to another node that the query was
+ cancelled.
+
+ Per shard locks, tasks, and threads.
+
+ When running within a single Journal, the query plan is executed by
+ one task which holds all of the necessary locks. Those locks are
+ acquired up front by an inspection of the query plan to determine
+ which indices are needed [actually, it may just be using the
+ unisolated read/write index and otherwise historical views w/o
+ locks.]
+
+ There are issues relating to execution of the joins under the
+ concurrency manager, both in order to have access to the correct
+ IIndexManager and in order to managing reads and writes against the
+ unisolated indices by acquiring the appropriate locks. The way
+ things work right now the upstream join tests a cache for the
+ downstream join task for a given shard. If there is a cache miss,
+ it sends a factory task which uses a singleton pattern to start a
+ join task executing with the appropriate locks under the concurrency
+ manager and then returns the proxy for that join task to the caller.
+ This guarantees that each join task has the correct locks, but it
+ does so at the expense of running one thread per join task. It will
+ be difficult to get around this one task per shard per join
+ constraint without going directly to the lock manager with the shard
+ lock requests. [Or just submitting a per binding set chunk task to
+ the ConcurrencyManager, which might not be that bad if the chunks
+ are chunky.]
+
+ ==> Given this, maybe it would be easiest to adapt the current join
+ execution to allow optional gotos by paying close attention to the
+ termination condition for the query? We could then refactor to
+ support BOPs within the same general control logic. A DISTINCT
+ filter could be yet another custom RMI thing layered directly into
+ the join logic.
+
+ Rather than defining an eval() method for each operator, we have
+ standoff interpretation of the pipeline operators (whether for
+ binding sets, elements, or solutions). The query plan could
+ encapsulate the local versus distributed execution with annotations
+ on the operators rather than interposing operators and those
+ annotations would be used to wrap the sink with one which marshells
+ the outputs onto NIO buffers.
+
+ - Pipelined chunk-wise nested index join. This is the existing
+ join algorithm. For each binding set chunk received on a node to
+ be joined with a given shard, we execute that chunk wise join and
+ emit the intermediate results. [When the join is optional, we
+ have an optional target and we send the binding sets which do not
+ join to that optional target.]
+
+ - multi-block io pipelined join. This is a version of the piplined
+ chunk-wise nested index join which accumulates much larger chunks
+ (mega chunks) of binding sets (potentially all intermediate
+ results) and then computes the join of that using the
+ operator-at-a-time approach for that mega chunk. The tradeoff
+ between this join and the pure operator at a time join is that we
+ can keep the intermediate results off the disk using this
+ approach but we may have to read the shard multiple times.
+
+ - operator-at-a-time shard wise multi-block-io join. This join
+ proceeds an operator at a time. Once the producer is done, it
+ computes the entire join using the intermediate results from the
+ prior join and a single multi-block IO pass over the shard view.
+
+ A tuple read from the shard joins if there exists a binding set
+ which is consistent with that tuple. For example, given:
+
+ :- ..., POS(A loves B), SPO(B loves C).
+
+ and the following intermediate results from the POS shard:
+
+ B0:[A=John, B=Mary, ...]
+ B1:[A=Mary, B=Paul, ...]
+ B2:[A=Paul, B=Leon, ...]
+ B3:[A=Leon, B=Paul, ...]
+
+ and the following tuples read from the SPO shard:
+
+ T0:(John loves Mary)
+ T1:(Mary loves Paul)
+ T2:(Paul loves Leon)
+ T3:(Leon loves Paul)
+
+ then we have the following joins:
+
+ (T2, B3) // T2:(Paul loves Leon) with B3:[A=Leon, B=Paul, ...].
+ (T3, B2) // T3:(Leon loves Leon) with T2:[A=Paul, B=Leon, ...].
+
+ There are several ways to manipulate the intermediate results to
+ setup the join:
+
+ Merge join: Merge sort the binding sets based on the relevant
+ bound values (A,B) and do an ordered scan of the binding sets and
+ the shard, emitting results which join.
+
+ Hash join:...
